Considering Rogue Audio or P.S. Audio

Currently have Rogue Audio Cronus Magnum Integrated and want separates.  I'm running them into Spatial Audio M3 Turbo S speakers at 4 ohms.  Considering the Rogue Stereo 100 and RP5 or RP7.  Also looking at P.S. Audio BHK Signature pre- and BHK amp.  I am aware the BHKs are more expensive but would like feedback on this comparison and if you have any other ideas (no shortage here I'm sure).
